Abstract (en)

[origin: WO8701822A1] The spontaneous formation of liquid crystal microdroplets by regulated phase separation from a solution of their isotropic state in matrix-producing composition, the matrix being solid and light transmissive synthetic resin, during solidification of such matrix yields a light modulating material consisting essentially of microdroplets (11) of liquid crystal dispersed in the matrix (10).
